Genset locomotive

A genset locomotive is a locomotive in which a number of smaller diesel engines are used rather than a single large engine. The term is short for "generator set."[1]

Aspects of gensets

A genset uses one to three small diesel engines to provide power. An operator is able to activate each engine as needed, with multi-engine gensets activating one for light work and more for heavier work, with excess engines turned off when the extra power is not needed.[1]

Advantages

  • More efficient design.
  • Longer service life.
  • Fuel savings.
  • Ultra-low emissions.
  • Improved wheel to rail adhesion capability.
  • With multiple engine gensets, should one genset engine fail, the others can keep the train going, albeit at reduced speed.
  • Removing a genset engine requires smaller size crane, while a larger crane is required to remove a traditional diesel prime mover.[1][2][3][4][5]

Disadvantages

  • More complex design.
  • Greater capital cost.
  • Greater deadweight.
  • More engines, and the engines and generators do not use standard parts, reducing reliability.
  • Multiple smaller truck type engines which lack the hardiness of a single large railroad type prime mover.
  • Engineers do not like them because they are slow to get a cut of cars moving.[2][6][5]
